Mine is out of warranty for 4 months, battery drained was bad as one side can only tahan less than an hour. I send it to the sony service centre and now I gotten an notification that I can collect but the amount this RM 444. Wth? Why would I pay that amount to get a 'replaced' XM4? I might as well don't collect and just throw away my 'old' earbuds.

Called the hotline and the lady say cannot discount or waive the charges.
